1997 7.3 Getting harder to start
1997 F-250, 7.3 liter, 78,0000 miles:
I know this is probably pretty basic, but it's my first diesel. Ambient temperatures around here are getting down to 30 F or so at night and around 45 F during the day. The truck is getting hard to start. Before the weather cooled down, it would start right up as soon as I turned the key after waiting for the "wait to start" light to go out. Now it takes three or four tries. It turns over fine. When it finally starts, it puts out white smoke that wasn't there before in the warmer weather. Once the engine is warm, there is little or no smoke of any color on start-up. What's the best way to diagnose so I don't go wasting money on unnecessary parts? Any tips would be greatly appreciated.
